Simple. Safe. Versatile.


The new BS series from DEDITEC.



DEDITECS BS series has been extremely successful on the market for almost 10 years now. Now the high-tech company from Brühl has added three additional analog I/O modules to its long-running series: BS-WEU-AD16, BS-WEU-AD16-DA4 and BS-WEU-AD16-DA4-OR16.


Already the previous modules of the BS series could optionally switch digital inputs and outputs via Ethernet, USB or CAN. Thanks to the new “WEU” core, the new modules now always support Ethernet, USB and Wifi. The BS-WEU even has both variants in one module: digital and analog inputs and outputs.


A special feature of the analog inputs and outputs is the galvanic isolation from the power supply. This means that technicians no longer need to ensure that the connected measuring sensors are at the same potential. This is because both the A/D inputs and the D/A outputs are now galvanically isolated from each other.


DEDITEC relies on a screwless system from the manufacturer WAGO-Kontakttechnik as the connector. The 1-conductor female connectors are 100 percent protected against mismating and have an extremely reliable ejector and locking mechanism. Incidentally, all types of conductors up to 1.5mm² can be connected. The female connectors are even pin-compatible with the NET series, making cross-series replacement child’s play.


Technical data in detail


Analog Inputs:

  • 16 channels with 16 bit each
  • Galvanic isolation to power supply: max. 500V
  • voltage ranges: 0-5V, 0-10V, +5V, +10V
  • optional current ranges: 0-20mA, 4-20mA, 0-24mA, 0-50mA
  • input resistance: >500kOhm


Analog Outputs:

  • 4 channels with 16-bit resolution each
  • Galvanic isolation to power supply: max. 500V AC
  • Voltage ranges: 0-5V, 0-10V, +5V, +10V




WEU stands for WiFi, Ethernet and USB. The BS-WEU modules can be configured and controlled wired via Ethernet (10/100Mbit) or USB (2.0/1.1) as well as wireless via WiFi with any DEDITEC software.


Setting up the modules with the company or home network is particularly user-friendly thanks to their three WiFi modes: WiFi ON, WPS Start and – if WiFi is not desired – WiFi Off. All modes can be easily set directly on the module using a button or via the included “Module Config” software.


The extensive Windows driver library (DELIB) enables a uniform and very simple control of the modules under almost all available programming languages. Furthermore, after the installation of the DELIB driver library, not only a ready-made configuration program, but furthermore also a test program is available. As expected, DEDITEC supplies the required software directly on the “DEDITEC Driver CD”. Alternatively, it can also be easily downloaded from By the way, the modules are fully software-compatible with the predecessor modules.


The BS-WEU modules also feature four status LEDs as well as an LED at each input and output channel. In addition, four DIP switches facilitate network configuration. The connection wiring of both modules is done via 16-pole stretchable female connectors. The modules are operated with a supply voltage of +7 to 24 V DC.



This module only has analog inputs and is perfectly suitable for monitoring voltages and currents. Transducers, for example, convert physical quantities such as pressure, temperature, humidity, etc., into corresponding currents (0..24 mA) or voltages (0..10 V) and can thus be recorded and digitally processed with our A/D modules.


The voltage range available is +-10V, +-5V, 0-10V and 0-5V. The ranges are configurable via software.



This module has additional analog outputs. With these you are able to control current or voltage controlled actuators like valves, servo motors or special power supplies. Especially in harsh industrial environments and with very long cable runs, analog signals, especially currents, can be transmitted interference-free.


The voltage range available is +-10V, +-5V, 0-10V and 0-5V. The ranges are configurable via software.



Digital inputs and outputs are added to the analog inputs. In addition to the analog inputs, digital signal states can be acquired within a voltage range of 5V to 30V AC or DC. The digital outputs are perfect for smaller switching loads.
